An apparatus for measuring radiation dose using the change in light absorbance of a transparent material upon irradiation which comprises substantially a light source, a monochromatic light emitting unit, a unit for controlling the light amount, a sample mounting unit, a detection unit and an indication unit wherein said light source is a hollow cathode lamp is herein disclosed.

Apparatus for measuring radiation dose

An N/P type silicon solar cell is doped with copper and encased in an aluminum sheath to form a probe. A heavy metal foil means is inserted in the probe to accomplish a solid state ionization chamber of silicon PN-junction type.
